Gerbera, also known as hibiscus flower, it is a very beautiful flower, not only beautiful flower shape, color is also very rich, loved by many flower friends. However, when breeding gerbera, sometimes we will encounter diseases and insect pests. These diseases and insect pests are very harmful to gerbera, so we need to find and control them in time. What about gerbera bugs? Next, let's take a look at the pest control of Gerbera chrysanthemum together with Xiaobian!

1. Gerbera grows insects and is sprayed with medicine.

Generally speaking, African chrysanthemum has strong adaptability and is rarely attacked by diseases and insects, but if we do not follow the breeding method of African chrysanthemum, it will also grow insects and get sick. At that time, flower friends must be very worried! What about African chrysanthemum bugs? In fact, it is very simple, first determine which kind of bug, and then control it. The following is the pest control of African chrysanthemum, there are a total of 4 insect pests and 3 diseases, we move on.

II. Disease and pest control of African chrysanthemum

1. Aphids

Plants are most afraid of being infected with insect pests, and African chrysanthemum is no exception, and among them, aphids are the most likely to occur. The insect mainly lives on newborn branches and feeds on sap. Symptoms: African chrysanthemum leaves become smaller and curled up.

Control methods: when a small amount of aphids are found, you can rinse with water, or scrape off the insects with bamboo slices, then spray 1000-2000 times omethoate solution, or kill them with tobacco water: 50 grams of tobacco leaves with 5 kilograms of water, boil.

2. Leaf mite

One of the main pests of African chrysanthemum whose larvae feed on mesophyll cells of leaves. Symptoms of damage: spots or twists and turns appear on the leaves of African chrysanthemum.

Prevention and treatment methods: when the above symptoms are found, 40% propargite 1000-1500 times or 20% mites EC 1000-2000 times should be sprayed regularly, generally once every 3-4 weeks, once every 5-7 days when the harm is serious, and 4-5 times in a row.

3. Thrips

One of the most harmful pests of African chrysanthemum is that its adults and nymphs feed on the juice of young tissues (shoots, leaves, flowers, fruits, etc.) of the plant. Symptoms of damage: gerbera leaves yellowed and withered, slow plant growth and shortened internodes.

Prevention and control methods: diseased leaves are removed in time and burned or buried deeply in order to reduce the source of the disease; when the disease is serious, 1000 times of 25% imidacloprid and 3000-5000 times of 25% thiazine can be sprayed for control.

4. Cabbage worm

One of the diseases and insect pests of African chrysanthemum, it mainly bites the leaves and eats all the leaves in severe cases, leaving only coarse veins and petioles, resulting in absolute yield and easy to cause the epidemic of soft rot of cabbage.

Control methods: the harm of Pieris rapae is mainly divided into larvae and advanced instar larvae, which need to be sprayed and sprayed several times in time to prevent the harm from further expanding. Commonly used agents are: 90% crystal trichlorfon 1000 ~ 1500 times liquid, or 50% dichlorvos EC 1000 times liquid spray and so on.

5. African chrysanthemum root rot

When it comes to diseases and insect pests, African chrysanthemum root rot is definitely one of the deepest damage, the disease is common, easy to cause African chrysanthemum wilt. Symptoms: the root of the disease is brown rotten and the cortex is easy to peel off. Several diseased roots gradually invaded the surrounding roots, causing the whole plant to wither and the roots to rot.

Prevention and control methods: diseased leaves should be cleared and burned in time to reduce the source of the disease. at the initial stage of the disease, fungicides such as 50% carbendazim 500-600 times or 70% methyl topiramate 800 times can be sprayed once every 7-10 days, 2-3 times continuously.

6. Mosaic disease

Mosaic disease is also one of the diseases and insect pests of African chrysanthemum, once suffering from the disease, it will seriously affect the ornamental of the plant. Symptoms: African chrysanthemum leaves are faded, deformed, have patches, and affect flowering or plant death.

Prevention and treatment methods: when the above diseases are found, 0.5% antiviral agent No. 1 300 times or 5% bacteriological clear water agent 400-500 times can be sprayed for prevention and treatment, once every 7-10 days, 2-3 times successively.

7. Powdery mildew

Powdery mildew, which is easy to break out in high temperature and unventilated environment, mainly harms the leaves of African chrysanthemum. Symptoms: the diseased leaves appear white spots and gradually enlarge.

Prevention and treatment: at the initial stage of the disease, fungicides such as 2000 times of 25% fenrucine or 65% of Dysen zinc can be sprayed. The effect is better when the medicine is used alternately.

With regard to the pest control of African chrysanthemum, this is the end of the editor's introduction. I believe that if you encounter African chrysanthemum worms or get sick again, you should know how to do it! Generally speaking, African chrysanthemum is rarely disturbed by diseases and insect pests, so as long as you take good care of it, these troubles will not be found. Finally, may your African chrysanthemum blossom beautifully.

How to raise Gerbera

African chrysanthemums are very popular in flower shops, but few people dare to plant potted plants. Everyone says that they do not understand, it is difficult to grow, and they do not know how to grow gerbera. I have planted it for a few years, but I think it is very good. I hope to share my experience with more people. This time I try to be as concise as possible. It's not as long as the last post, for your reference.

[characteristics of African chrysanthemum]

1. Xiguang: when there is no shortage of water, it becomes stronger and stronger, grows faster and blossoms more.

2. Like fertilizer: like dwarf cattle like fat, if you want to blossom more, fertilizer should keep up.

3. Drought tolerance: well-developed fleshy roots, strong water absorption, but avoiding waterlogging, which is the main reason for her immortal to go, proper water control is the safest not to wilt (more on later)

4. Temperature: the suitable temperature for flowering is 15-30 degrees, in which the flowers continue to blossom, the limit tolerance temperature is 5-40 degrees, the growth stops below 7 degrees, the growth slows down in the high temperature season, but it will not become weak and will blossom sporadically, so the flowering period is in March-May and September-November in Spring and Autumn.

Diseases and insect pests: this is the Achilles' heel of African chrysanthemum and all Compositae plants. Those who have raised chrysanthemums know that they are the magnets of insects and should be detected and treated as soon as possible. The disease is mainly fungal root rot crown rot, that is, commonly known as rotten roots, rotten stems, watering methods should pay attention to a little can be avoided.

6. Flowers: the conventional variety Flower diameter 8-12cm, covering all colors except blue and purple, the color is warm, beautiful and warm. The single flowering period is very long, and the vase can not wither for more than half a month, so it is suitable to be used as a cut flower.

7. Maintenance difficulty: the habits are similar to those of geraniums, and they are not resistant to waterlogging. African chrysanthemum is much more heat-resistant than geranium, but there are also more diseases and insect pests than Xiaotian, which requires key prevention and control. She does not need frequent pruning, watering frequency is also low, comprehensive consideration is a relatively good species of herbaceous flowers easy to raise. We do not have to worry about buying home to raise or difficult to recover flowers, buds are constantly growing, there will not be a permanent silence after blooming only once.

[African chrysanthemum conservation]

1, basin soil: the basin does not need to be too big, large ones use 18cm, medium 15cm, mini varieties 12cm can, the soil must be aerated and permeable, peat: perlite = 2:1 or with other media instead, the market with peat-based culture soil can also, such as Cuiyun and so on.

2. Lighting: the more the better. For example, I only have an eastward closed balcony. Four hours of direct light a day is the limit for the normal growth and flowering of African chrysanthemum. If the dwarf can grow normally, then the African chrysanthemum will be fine.

3. Moisture: contrary to light, the supply should be properly limited. Don't rush to water the adult plant you just bought. You can often touch the leaves with your hands, but you don't need water if you are stiff and stiff. The best time to feed water is to soften but not wilt a little. At this time, most of the basin soil is still dry, and you can immediately water it thoroughly. If you touch the leaves within half an hour, you should have become stiff. This is a sign of normal root function (strong water absorption), which is different from the rotting root plants that often wilt. And there are no symptoms of rapid improvement after watering (this condition tends to wilt more and more serious, resulting in plant death). Watering should be careful not to pour fat water into the heart of the leaf, especially on the bud, which may make the bud rot and increase the possibility of stem rot.

4. Fertilizer: be adequate and balanced. Like other herbs, if you want to grow strong, use balanced fertilizers such as nitrogen, phosphorus and potassium, such as Biwang, Huaduo 1, or any other organic fertilizer and chemical fertilizer. Adult plant to promote flowers with high-phosphorus and high-potassium fertilizer, must blossom, Huaduoduo 2, potassium dihydrogen phosphate, flower liquid fertilizer and so on, before planting can add sufficient base fertilizer, cake fertilizer, chicken manure, bone powder can be mixed with the best. Nitrogen fertilizer should not be too much, otherwise the leaves are thick and crowded, just like green vegetables, affecting the development of flower buds.

5, prevention and control of diseases and insect pests: red spiders, whitefly, aphids, shell insects, thrips may occur, especially the first three common, early detection and early treatment. Her leaves are broad and relatively simple, so she pays attention to both the leaf surface and the back of the leaf. There are several kinds of diseases, but we often see only one kind of rotten root, as long as a certain amount of light is guaranteed and watered according to her needs, it will not happen.

Once the symptoms of wilting, scorched leaves and soft flowers appear, we should be vigilant, stop water and fertilizer in a ventilated place, spray water properly to keep the plant from dehydration, and wait for the root system to grow well again. If it is serious, it is necessary to turn the basin and change the soil immediately, cut off the rotten roots, replant it, and pay attention to moisturizing.

6. Cut flowers: cut the cylindrical flowers of the inner wheel after flowering for one or two rounds, or shake and fold them repeatedly with your hands, cut them diagonally into clean water, often shorten the soft pedicels, change water, and add antistaling agents to prolong the flowering period. Cut flowers can bloom longer than those left on the plant, and if the pedicel is tall and unattractive, it is also a good choice to cut off and watch.

[gerbera gerbera reproduction]

1. Ramet: a healthy plant grows several bad buds in a year, so that many flowers bloom at the same time. When the plant becomes crowded, its growth weakens. It is generally necessary to split the plant every three years and cut it with a sharp blade. Each plant should have one to several terminal buds and enough roots to disinfect the wound.

2, cutting: this operation is inconvenient, to sum up is to cut off the head, and then use a large number of lateral buds cuttings, I have not tried, and do not recommend you to use.

3. Seeds: it is better to use imported ones. The self-flower sterility of Compositae plants requires at least two different African chrysanthemum plants to pollinate each other in order to bear fruit. The offspring vary greatly, and excellent new varieties may appear, but most of the progenies do not have ideal flower diameter and great variation in flower color, so self-harvesting seeds are not recommended for propagation.

One day, the emperor wanted to try the literary talent of Han Lin, so he asked him to write a poem with the title of cockscomb flowers. Jie Jie, of course, was unambiguous, and he blurted out: "the chicken crown was originally dyed with rouge."... " As soon as the words fell, the emperor suddenly took out a long-prepared white chicken crown flower from his sleeve and said to it with a smile, "this is white." Xie Huan saw an idea and immediately changed his tune and said, "how light makeup is today?" He is only eager to report the news for the fifth shift, but he is still wearing frost all over his head. " It is very clever to replace the red cockscomb flower which has just opened and chanted into a white cockscomb flower. The emperor and the people present all admire the cleverness and talent of Xie Yi.

For literature lovers, as long as cockscomb flowers are at home, they most think of these intoxicating sentences, I have to say, cockscomb flowers add a lot of interest to our lives.

Culture methods of Celosia cristata

The following introduces the maintenance of cockscomb from the basic requirements to the special requirements.

First, the basic requirements of its life:

1. Rough raising of cockscomb from the point of view of personality. Cockscomb likes sunshine, is resistant to barren, afraid of stagnant water, is not resistant to cold, and grows well in a high-temperature and dry climate. Under normal circumstances, there is no need to water or fertilize. Cockscomb can be used as a potted ornamental flower. Potted plants generally do not need to plant seedlings in pots, but choose to plant cockscomb flowers in the pot at flowering stage. Plant a little deeper when potting, so that the leaves should be close to the surface of the potted soil. Do not scatter when transplanting, water thoroughly after planting, fertilize after 7 days, and apply liquid fertilizer every half a month. Before the inflorescence is formed, the basin soil should be kept dry to facilitate the breeding of inflorescences. After the bud is formed, liquid fertilizer can be applied once every 7-10 days and properly watered.

2. Prevention and treatment of common diseases of cockscomb. When root rot occurs in the seedling stage, it can be sowed in the field with quicklime. Small bridge insects are easy to occur during the growing period. Foliar spraying with diluted detergents, dimethoate or pyrethroid pesticides can play a role in prevention and control, reproduction and cultivation.

(1) Ring disease, the main symptom is the appearance of large brown round disease spot on the periphery of the leaf, and there are obvious concentric wheel lines on the surface of the disease spot, and then the center of the disease spot is grayish brown and scattered with small black spots.

(2) Blight disease, the main symptom is that the leaf is dark green at the beginning, then expands, and the spot is soft rot in high humidity, light brown and dry in low humidity.

(3) spot disease, the main symptoms are polygonal or round spots on the leaves, 1-5 mm in diameter, dark brown in the periphery and light brown in the middle.

(4) Rhizoctonia solani, the main symptom is that the pathogen mainly infects the root and stem. Disease occurred before emergence, seed buds rotted in the soil, showing lack of seedlings on the ground, disease occurred after emergence, the damaged rhizome showed dark brown, softened, watery, the top of the plant withered in the later stage, and finally withered. When the disease is serious, the leaves in contact with the ground are also easy to produce dark green to brown watery spots, causing leaf rot.

(5) Stem rot, the main symptom is that the disease is mostly harmful to the base of the stem, the yellow-brown spot appears at the initial stage, and then it gradually expands into an oval or long spot, the edge is brown, the central yellow or gray-white, and finally there are small black spots on the spot.

3. Governance mainly starts from two aspects.

(1) timely spraying and prevention in the early stage of the disease, including Bordeaux solution of 1purl 200, 50% methyl topiramate wettable powder, 50% carbendazim wettable powder 500 times liquid spray, 40% carbendazim suspension 600 times 800 times liquid spray, or watering with Dyson zinc wettable powder 300 times 500 times liquid.

(2) in addition to using diluted detergents, modern ways to protect the environment can also plant plants that keep insects away, or put beneficial insects that eat those pests.

Second, the special requirements of its life:

If you want to make the cockscomb plant stout, the Corolla is fat, thick and colorful, you can change a large pot after the inflorescence is formed, but you should pay attention to the fact that it cannot be scattered when transplanting, because its root is extremely weak, otherwise it is not easy to survive. Celosia cristata is cross-pollinated, and it is easy to cross and mutate among varieties. Therefore, the flowering period of the remaining varieties should be isolated. When keeping seeds, the seeds in the lower part of the inflorescence should be harvested to retain the characteristics of the variety. There are many varieties of cockscomb, with three plant types: tall, medium and short; the shapes are cockscomb, torch, cashmere, feather, fan, etc.; the colors of flowers are bright red, orange-yellow, dark red, purple, white, red-yellow and so on; the leaves are dark red, emerald green, yellow-green, red-green and so on, which make them a commonly used flower bed in summer and autumn. In cultivation, if the management and maintenance is improper, the flowers are often rare and the color is dim, which affects the ornamental value of cockscomb. In order to make the cockscomb flowers big and colorful, we should pay attention to the cultivation and maintenance:

The main results are as follows: (1) planted in sandy loam with high dry, sunny, fertile and good drainage.

(2) watering should not be excessive during the growing period, watering should be controlled after flowering, watering should be appropriate when the weather is dry, and timely drainage should be carried out in cloudy and rainy days.

(3) all axillary buds were removed from seedling stage.

(4) after the chicken crown was formed, the thin compound liquid fertilizer was applied 2 or 3 times every 10 days.

The above is for everyone to introduce the efficacy and function of cockscomb and breeding methods, more household plants, please pay attention.
